Launching the Blood Sacrifice Formation requires an extremely large amount of energy as support, and Blood Food is one of the sources of these energies.

Blood food is also good and bad, still in the pregnant woman's womb, the embryo to be formed is the best choice, followed by the infant baby, according to the age of the decreasing order, and finally the adult heart.

This is also the reason why in the dungeon, the stumps and broken arms all over the ground are from adults.

The Blood Sacrifice Formation is different from the ordinary formation, it does not have the ability to transfer thousands of catties in four or two and get twice the result with half the effort, and even on the contrary, the moment before the formation is launched, the energy required is almost more than the sum of the previous preparations.

Therefore, the Chen family saved the most valuable blood food for the end, and waited until the day of the feast to use it.

The theoretical cornerstone of the rescue plan lies in this, and it is such a gap that the two elders want to grasp.

Saving the blood food, so that the Eight Yin Lianjiao Xuan Demon Array was powerless and incapable of activation, thus dissolving the Chen family's plan into invisibility.

"It's better to choose a day than to hit the day." Elder Xu said solemnly, "You guys each prepare and set off after a stick of incense." ”

……

Midnight, sub-hour.

Ning Ziyi, who was dressed in the Lingyin cloak, followed the route of the last time to sneak into the cave, shuttled through the intricate corridors with ease, and soon came to the dungeon.

However, this time, he had already established psychological preparation, but his pupils still shrank.

The candle flame was still there, the smell of fish was permeating, and there were even red blood stains on the ground.

However, in the rusty cage, the door was wide open and empty, and even the children of the Chen family who were patrolling were nowhere to be seen.

When Ning Ziyi's heart was still shocked, an eight-treasure gourd that he hung on his waist suddenly shook, and then a majestic voice sounded in his head.

"They moved on, and went to the fifth corridor ahead."

It was Elder Sui's voice, and this Eight Treasure Gourd was also Elder Sui's magic weapon.

It turned out that Elder Sui's Eight Treasure Gourd was a spatial magic weapon that could be sucked into it and released at any time.

He used the characteristics of his gourd and combined it with Ning Ziyi's invisibility cloak to come up with such a wonderful combat method.

That is, the rest of the people, including himself, were sucked into the gourd and carried by Ning Ziyi, so that he could sneak into the cave without being discovered by anyone.

But this method is only applicable in the first half of the journey, because the space of this eight-treasure gourd is limited, and like now, it can accommodate a full sixteen adults, which is almost to the limit, and it is basically a crowded state.

Yes, sixteen people, that is, Chen Susu is also among them.

Although the two elders did not say it explicitly, Chen Susu's true identity obviously could not be hidden.

She is the owner of the body of the Taiyin.

Even if there are still many mysteries in between, it should be true, otherwise there would be no other explanation.

Chen Susu did not raise any objections to the arrangement of the two elders, but was silent throughout the whole process, lowering his eyes, not knowing what he was thinking.

In the dungeon, Ning Ziyi followed Elder Sui's instructions and went deeper into the center step by step, and finally found the children who were imprisoned together after changing more than a dozen corridors in a row.

Even though I have already seen it in the shadow stone, the images that can be preserved are still not as good as what I have seen with my own eyes.

Elder Sui gave an order to lift the ban on the Eight Treasure Gourd, and the extremely angry disciples rushed out one after another, and in an instant, colorful energy fluctuations swept through, and within a moment, the children of the Chen family who were guarding here were completely wiped out.

The two elders had already built a divine sense barrier in advance, and the movement of their actions was completely concealed.

"One, two, three...... Twenty-seven, twenty-eight......"

A female disciple in the middle stage of foundation building was counting the number of children, and at the end of the count, her expression changed suddenly.

"No, I counted when I was watching the video before, and there were obviously thirty-two people at that time!"

"It shows that these four have been turned into nourishment for the evil law."

Ning Ziyi's face was also ugly, how long has it been?

These people in the Chen family are really crazy.

"Ahem, ahem...... Big brother, big sister, are you here to save us? ”

Huddled in each other, huddled in the corner of the cage and shivering, a half-grown boy who looked a little older was covered in dirt and asked timidly.

"yes." The female disciple showed a gentle smile, and with a wave of her hand, she opened the prison door, "Come out, my brothers and sisters will protect you." ”

When the boy heard this, he did not come out immediately, but seemed a little hesitant, and only after a moment did he take a step, and under the surprised gaze of the female disciple, he knelt down in front of her with a pop.

"I know my brothers and sisters are good people, please go and save my brother! He was captured by those bad guys, not long ago......"

As he spoke, the boy was about to grab the ground with his head, but was stopped by the female disciple with her hand.

She looked embarrassed, "It's not that my sister doesn't want to help you, but ...... Your brother is probably hopeless. ”

"Impossible, absolutely impossible!" The boy shook his head frantically, almost shaking out the afterimage, "He will be arrested a moment before you come, and even if something happens, it will definitely not be so soon!" It's really a meeting! ”

The female disciple was a little helpless, and just as she wanted to continue persuading, she heard several other children also speak.

"My sister is ...... too"

"And my ......"

She was stunned for a moment, and then reacted, if you add the few people these children said, it will be exactly thirty-two people, could it be that it is really such a coincidence......

"No."

At this moment, a figure stood in front of the female disciple, and it was the only one who had been recruited in the late stage of foundation building.

His expression was grim, and he didn't explain much, but escorted the female disciple step by step, and said indifferently.

"It can't be saved. If you want to live, be obedient, and if you don't want to live, we will not stop you. ”

The boy obviously didn't expect to get such an answer, and for a while, there was only the indifference of the cold male cultivator in his eyes, and as for the female disciple's shouting and questioning, he was completely shielded by him.

He began to mutter, "Why...... Didn't they say that just pretending to be pathetic can make you take the bait...... Why, why don't you listen to me and don't save people......"

"Why!"

The boy suddenly screamed and asked, his eyes were bleeding and tearful, as if he was crazy, and he actually landed on all fours, like a vicious dog, and bit towards the cold male cultivator.

At the same time as the boy changed, several other children who had opened their mouths also mutated at the same time, and they were locked in another cage with the door open, so they turned their heads and bit their companions.

This sudden change stunned the female disciple.

Before she could react, she saw blood splattering, and it was the cold male cultivator who shot mercilessly, killing all the children who had undergone the mutation, without causing further damage.

"These children have been bewitched by malice, and they have fallen into the devil." He said, "Before they are completely controlled by the demonic nature, send them to reincarnation, so as not to enter the soul of the demonic nature, and they can only be demons in the next life." ”
